Strike King Pro-Model Series 4S Bait The Strike King Pro-Model Series 4S features the same body design as the popular Series 4 but is designed for shallow applications. It crawls through all types of thick shallow cover with its unique wide wobble design and square bill. The shallow, cover-laden stained water domain of the spinnerbait angler can now be conquered with our Series 4S. Dives from 2 to 5 feet. All Pro-Model Crankbaits feature free-floating rattles and lifelike 3D eyes.
